Barricades impede enemy movements and provide protection for any defending survivors positioned behind them. They also provide a Security bonus and can have one survivor assigned to them. Upgrades to this structure improve its Security bonus, health and Cover rating.

Level 1: The small barricade takes the form of a small pile of sandbags arranged in a wall. Two vertical pieces of wood is nailed to both ends on top of the sandbags and a plank is laid across the two vertical pieces of wood.

Level 2-3: a piece of corrugated iron and a metal plate are placed in front of the sandbags for added durability.

Level 4: Wooden supports are placed along the back of the small barricade and barbed wire is strung across the top of the small barricade.

Level 5: Another piece of metal is nailed between the corrugated iron and the metal plate near the top of the small barricade and more barbed wire is strung across the top.
